SPRAY-NOZZLE FOR HUMIDIFIERS.

Specification of Letters Patent.

Patented May 11, 1909.

Application filed December 31, 1908. Serial No. 470,225.

To all whom u may concern;

Be it'known that I, STUART Y. CRAMER, a citizen of the Unit ed States, residing at Charlotte, in the county of Mecklenburg and State of North Carolina, have invented certain new and useful Improvements in Spray- Xozzles for Humidifiers and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates primarily to humidifiers for moistening the air in mills, factories and other buildings and has espe cial reference to an improved Water spray nozzle.

The particular form of spray nozzle to which my invention refers, and to which it is applicable, is that consisting of a body member arranged for attaching to a supply pi e, a jet discharge orifice, either incorporate 1 directly into the body part or into a detachable member adjustably secured thereto, and a yoke uponwhich is supported a jet breaking up pin, opposite to and concentrically arranged with reference to the, discharge orifice.- In all the'lvarious modifications of this type of spray nozzle, great ditiicultyis exerienced in preventing the discharge orifice om becoming stopped up with even fine particles of foreign matter. Numerous devices have been tried to-accomplish this desirable result; some of them are based upon the principle of screening out the foreign matter with a line mesh screen, but the most satisfactory consists of a standpipe so arranged With reference to the water supply inlet that particles of foreign matter do not drop directly into the standpipe, but are deposited elsewhere, the Water itself having to enter the standpipe through a circuitous route and thence out through the discharge orifice. Heretofore these standpipes have either been made as a part of the integral portion of the body member, or of the detachable member containing the discharge orilice, or have been made separate and screwed into those parts becoming thereby more or less a part of them. Even if the standpipe is detachably secured to the other parts by being screwed thereto, it is obvious upon reflection that when the standpipe is screwed out for cleaning, or otherwise, that foreign particles around it will drop into the orifice and clog it up. The object of my inventiomtherefore, 'isto .With the dish provide an iinprovedand simpler form of construction whereby not only may foreign particles present in the Water supply be prevented from going into the discharge orifice and thereby stopping it up, but also a form of construction whereby these foreign particles are caught and easily and expeditiously removed.

The invention consists in certain improvements which will be fully disclosed in the folmember, detached. Fig. 4 represents a perspective of the detachable member containing the discharge orifice and the jet breaking up pin, and also showing the chamber in the neck for receiving the standpipe and into which the body member is screwed, and Fig. 5 represents a perspective of the stand pipe on its lower end detached.

Reference bein had to the drawings and the designating characters thereon, the numeral 1 indicates the body member.

.2 is the water inlet to the body member into which the supply pipe (not SllOW'll) is screwed.

3 is a'sliield inside the\body member, so that the water entering Will be diverted through passages 4 toward the Wall of the bod y member. a

5 is recess in the lower sideof the shield into which the stand pipe 6 projects.

7 is passage extending longitudinally tl'irough the stand ipe and through which ater is adniittei-l 'ron the body member I to the discharge orifice The discharge orifice 8 is formed on a diet. enable member or yolre 9, wh ch also, supportsa pillar 10 on which is a breaking up pin 11 adjacent,

to and opposite the orifice 8. The. upper portion or neck Wot this ceti-ichabie member is provided s'ith a ch inbcr 12, into which the lower threaded endi of the body member 1 is screwed, and also furnishes a seat- 13 for the lower end of the standpipe 6, which terminates in a flat disk like portion 14. Below the disk 14 is .a conical recess 15 in Which any impurities in the Water coming through the passage 7 accumulate. It is obvious that the same results could be ob- Fig. 2 represents a cross section of' tained by making this disk of othershape than flat, although the flat disk is thep'referred fornn I I u 1 The body member 1 is screwed to a su ply ipe, not shown. In order to clean t e 11022 e, the detachable member 9 ismerely unscrewed from the body member 1, carry' ing away with it the standpipe 6 resting on the seat 13. The standpipe-is then lifted out of the-chamber 12, carrying with it onits disk like portion 14 any foreign matter or sediment that has been deposited there; it is then but the workof a moment to blow this sediment off the disk 14, and off the smooth recessed portion 15 of the detachable member 9, when replacing the standpipe 6 in the chamber 12 of the detachable member 9 and screwing it back on to the body member 1 restores the nozzle to working condition;

,That the standpipe efiectuallyseparates heavy or coarse particles of foreign matter is quite clear, because the water entering the body member 1 is guided to one side of the o ening 7 in the standpipe 6, the velocity of t e water in the body member is comparawhat I claim is' e 1. In a spray-nozzle, a member adapted to be secured to a water supply-pipe, adetachable member provided with a discharge orifice, and a stand-pipe extending up into the first member and removable therefrom throu h the lower end thereof.

2. n a, spray-nozzle, a member adapted to be, secured to a water supply-pi e, a de- I tachable member PIOVIdGd'VVltll a ischarge orifice,. anda standpipe extending up into the first member and having adisk at the lower end thereof and above said discharge orifice, said stand-pipe and disk being re movable from the first member through the lower end thereof. I

3. Ina spray-nozzle, a body 'member, a member detachablysecured to said body member and provided with a discharge orifice, and a standipe through which water is supplied to sai orifice, resting upon and removable with said latter member.

- 4. In a spray-nozzle, a body member, a

member detachably secured to vsaidflbfody member, and provided with a discharge orifice-,and a disk for protecting sald orifice, resting upon-and removable with said latter I member. r

5. In a spray-nozzle, a bodymeniber, a"

member detachably secured to saidbody member and provided with a discharge ori-' fice, and a standpipe*provided with means 1 for arresting and removing foreign matter,

restingupon and removable with said latter member.

6. In ,a spray-nozzle, a. body member, a

member detachably secured to said body member and provided with a discharge orifice, a stand-pipe having. a. disk at the lower end thereof, and removable withthe latter member from the body member.

7. In a spray-nozzle, a body member, a member detachably secured to said body member and rovided with a discharge orifice, a charm er above the or1fice,. and astand-pipe in said chamber and with means for protecting said ori ing upon and removable with said latter member. y

8. In a spray-nozzle, a body member adaptiprovided ed to be attached to a supply-pipe at one end, a member provided with .a discharge orifice and means for breaking up a jet of water, and detachably secured to the opposite end of-said'bo'dyanember, a stand-pipe having a disk at its lower end and removable with the latter membenand'a shield above the upper .end of said stand-pipe and passages around said shield.

In testimony whereof I act; my signature in presence of two witnesses.
